Exar – XR1008/XR2008 AND XR1009/XR2009: Low Power Rail-to-Rail Amplifiers

XR1008/XR2008 AND XR1009/XR2009: Low Power Rail-to-Rail Amplifiers

The XR1008/XR2008 are single/dual amplifiers offering 75MHz bandwidth while consuming only 505µA supply current and the lower power XR1009/XR2009 single/dual amplifiers provide 35MHz at only 208µA supply current. When compared to other competing products on the market today, the XR1008/XR2008 devices offer 6 times the bandwidth and even the lower power XR1009/XR2009 devices offer 3 times the bandwidth. The XR1008/XR2008 single/dual amplifiers target industrial applications such as smart meters, ultrasonic heat meters and other applications requiring high speed and low power. The XR1009/XR2009 are single/dual amplifiers with an ultra low 200µA supply current for portable instrumentation and applications such as interactive whiteboards.
